The post is true, in that there no shared panels between E46 sedan and E46 coupe. But what I was refering to is that the design language between the two E46 variants are the same, they are styled to look similar. With the E90 and E92 they where styled to look as two separate models each with their own design language, hence a separate model name E92. With the 4series its been taken to a different level.
